GetError
Syntax ErrorCodeT WINAPI GetError(DevHandleT devHandle, LPSTR
errText);
devHandle refers to either the IEEE 488 interface or the external device that has the
associated error.
errText is the string that will contain the error message. If errText is non-null, the
string must contain at least 247 bytes.
Returns -1 if error
otherwise, it returns the error code number associated with the error for the specified device.
Bus States None
Example errnum = GetError(ieee,errText);
printf(“Error number:%d;%s \n”errnum,errText);
See Also Error, GetErrorList, Status
The GetError command is user-called after another function returns an error indication. The device
handle sent to the function that returned the error indication is sent to GetError as its devHandle
parameter. GetError finds the error associated with that device and returns the error code associated with
that error. If a non-null error text pointer is passed, GetError also fills in up to 247 bytes in the string.
The application must ensure that sufficient space is available.
